QoS might increase the CPU demand but NAT is fairly hungry alone. Some routers implement "hardware NAT" in order to get close to Gigabit speeds but that is not supported by OpenWRT (as far as I know it's not even planned but my information can be pretty outdated on the subject) and it might come with other restrictions on factory firmwares. Without that trick, you need a really fast CPU. I don't know if OpenWRT can make use of multi-threading on dual-core SoC when doing NAT. The qdisc stuff is used by the new Smart Queue Management which seems to be working very well on my router, although I have 60/5 speeds only. _______________________________________________ openwrt-users mailing list [email protected] https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-users
